speakers arent working

I am running windows on a dell. But any of you who run vista in a mac or windows pc should know, hopefully. If you click control panel on vista then type in sounds and click on Sound(picture of a speaker) under playback it should show your laptops speakers, well if you right click you see disable. I clicked that and then it deleted the speakers off of the list, now they don't work, how do I fix this???

They should be detected again on the next reboot. If they're not, try removing the sound device from the hardware tree and reboot. Vista will "see" it and the speakers again. In some cases, you may have to run the detect new hardware wizard.
